Creating MSVC Build Files via CMake

This is a simple "How-to" for creating build files for Microsoft Visual C++ via CMake and the CMakeLists.txt file

1. Install CMake if you haven't got it already ([http://www.cmake.org], minimum version required is 2.8).

1. If you want ASIO support you need to D/L the ASIO2 SDK from Steinberg, and place it according to Building Portaudio for Windows with ASIO support using MSVC

1. Run the CMake GUI application and browse to source files directory and build directory: a. The source files directory ("Where is the source code") is where the portaudio CMakeLists.txt file is located. b. The build directory ("Where to build the binaries") is pretty much anywhere you like. A common practice though is to have the build directory located outside the source files tree (a so called "out-of-source build")

1. Click Configure. This will prompt you to select which build files to generate. Note Only Microsoft Visual C++ build files currently supported!

1. In the CMake option list, enable the PORTAUDIO_xxx options you need, then click Configure again (Note that after this there are no options marked with red color)

1. Click Generate and you'll now (hopefully) have your VS build files in your previously defined build directory.

Both ASIO and DirectX SDK are automatically searched for by the CMake script, so if you have DirectX SDK installed and have placed the ASIO2 SDK according to point 2 above, you should be able to build portaudio with !DirectSound and ASIO support.

Should you later on decide to change a portaudio option, just jump in at step 5 above (MSVC will then prompt you to reload projects/solutions/workspace)
